i am afraid it may not be long enough tobe really specific,
 unless the DNA template is so pure that you are sure there is
n  othing else to amplifye! A quick way to test your primers
 is to screen Genbank with them. Also I think it is better
 to have a G/C  content closer to 50%
Good luck. Let me know the result of the search through databank.
